Forwa-Mould , locating in Dongguan, China, is a professional
plastic injection mould manufacturer with years experience in this
field. We can provide high precision complex hardened moulds,
prototype and soft moulds.

We equipped high speed CNCs, Wire cuts in house. We use software
(i.e. UG, Pro-E, IGS, Master Cam, AutoCAD, and Solidwork ) for
mould design and MoldFlow analysis for our customers before mould
manufacturing. Standard components we use to build the mould are
purchased from DME, HASCO etc. Also, COC for all steel we purchase
will be provided.

Mold Threads empowers engineers to achieve their vision for custom
molded parts in function, durability, and quality while maintaining
the integrity of the design.

Male threads are less complicated to produce than female threads.
Male threads are cast as an open and shut injection mold except in some instances where the rest of the part design
dictates where the parting line will be located. If male threads
need to be cast in the vertical position, the use of cam action or
hydraulic action slides is required because of the undercut that is
produced from the thread.

On the contrary, casting female threads always present an undercut
situation. These type of threads need to be unscrewed in order to
have the part removed from the injection mold. There are different
ways to achieve this. The most common way used is by hydraulic or
electrical motors that automatically unscrew the threaded core from
the molded part. The hydraulic motor is the least expensive option.
Threaded cores have wurm gears attached which mate with the main
drive gear. There is a chain that connects the mold drive gear to
the gear on the drive motor shaft. There are a few different
options of unscrewing the cores which are sometimes dictated by the
part design. The most common application is after the injection mold opens, the cores are unscrewed by the actuation of the unscrewing
motor. The time can be set so the motor stops once the part is
unscrewed off the core. In this application the part needs to be
held in place so the part does not turn during the unscrewing
cycle. This can be achieved by a variety of designs. Again, this is
always dictated by the part design. In some instances the threads
need to be unscrewed before the mold opens. This is achieved by
timers and/or the machine control. Usually, this option of molding
female threads is incorporated for high production parts because of
the expense involved.

In the case of low volume and prototype injection molded parts, the female threads are cast with hand-loaded cores. In this
process threads are commonly ground on three hand-loaded cores. One
core needs to be loaded into the mold by the means of locating pins
to position the core into the mold open position. The mold then
goes through the injection molding cycle. After the mold opens, the part is ejected with a
hand-loaded core attached. Another hand-loaded core is inserted
into the mold. During the next molding cycle the hand-loaded core
that was ejected with the part after the previous cycle is manually
unscrewed from the injection molded part. This process usually
doubles the cycle time of the injection molded part which in effect
raises the part price but is very cost effective in producing
prototype parts.

Another option to cast female threads is by the use of collapsible
cores, but this is a very expensive option. By the use of these
collapsible cores essentially the injection mold is considered an open and shut mold.

These are some of the most common options of producing threads on
injection molded parts. These threads are able to be cast to a +/-
.002 tolerance.
